<h2>Automatic Software Updates</h2>
[<a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#top">top of page</a>]&nbsp;&nbsp;&nbsp;
[<a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#start">next&nbsp;section</a>]<p>
Before using Exceed for the first time, it's a good idea to check for software updates on
Hummingbird's website.  Exceed includes a tool to do this automatically, called Hummingbird
Update.  To run it, open the "Hummingbird Connectivity Vx" program group (on the Start menu
under programs, or on the desktop), open the System Administration sub-group, and choose
"Hummingbird Update".  Click "Yes" if prompted to install any updates.  It is a good idea
to check for updates periodically.  Information about important updates will also be posted
on the <a href="http://www.udel.edu/topics/connect/sw/exceed/docs/addenda.html">addenda and errata</a> page, as it becomes available.
</p><p>

</p><h2>Starting&nbsp;Exceed</h2>
[<a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#top">top of page</a>]&nbsp;&nbsp;&nbsp;
[<a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#updates">previous&nbsp;section</a>]&nbsp;&nbsp;&nbsp;
[<a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#housekeeping">next&nbsp;section</a>]<p>
There are three ways to connect to remote systems and open X applications with Exceed:</p><p>
<b><a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#secure">X11 tunneling via SSH</a> is the most secure method</b>.  All information
passed between your PC and the host system will be encrypted.
</p><p>
<b><a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#xdmcp">Connecting via XDMCP</a> is less secure than SSH tunneling</b> (information
sent between the systems is <i>not</i> encrypted), but still provides some measure of security
by preventing other users from opening spurious windows on your machine or otherwise interfering
with your sessions.
</p><p>
<b><a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#nonxdm">Unmanaged connections</a> (using procedures such as rexec or rlogin) are
INsecure, and may allow other users to tamper with your system</b>.  In general, it is
ill-advised to connect in this fashion unless the host you are connecting to supports neither
SSH nor XDMCP.
</p><p>
<b><font color="#FF0000">NOTE to off-campus users</font></b>: If you connect to the Internet
via cable modem or DSL, or you have multiple computers sharing your internet connection and
the computer running Exceed is not directly connected to your ISP (this includes Windows'
"Internet Connection Sharing", many cable/DSL routers, etc.), then it is possible that only the
<a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#secure">X11 tunneling via SSH</a> method will work without requiring changes to your
home network setup.  The tunneling via SSH method will work as long as you are able to open a
secure shell session on the remote host.  If you wish to use one of the other methods, you may
need to contact your ISP's techincal support for help in reconfiguring your equipment.
</p><p>
<a name="secure"></a>
</p><h3>Tunneling&nbsp;via&nbsp;SSH</h3>
This is the most secure method for using Exceed, and is highly recommended.
In order to connect via this method, you will need an SSH client which supports
X11 tunneling.  One such client for Windows is available from SSH.com, and is
free for academic and personal use.  You can 
<a href="http://udeploy.udel.edu/Win/Docs/ssh.html" target="ssh">
download a copy</a> from the University's software distribution site.
The installation is automatic.  To enable X11 tunneling:<br>
<ol>
  <li>Run the SSH program.
  </li><li>Click the "Edit" menu and choose "settings".
  </li><li>Click on the "Tunneling" sub-heading (under "Profile Settings")
  </li><li>Check the box next to "Tunnel X11 connections" on the right.
  </li><li>Click the "OK" button.
  </li><li>Click the "File" menu and choose "Save settings".
</li></ol>
(For instructions on setting up SSH tunnelling in other SSH clients, refer to the
documentation for those clients.)<p>
To run X applications on a remote host and tunnel their output via SSH to Exceed on
your PC:<br>
</p><ol>
  <li>Start the Exceed server in passive communications mode (if you configured
      Exceed with the recommended settings from the
      <a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-configuring.html">configuring Exceed instructions</a>, 
      it is already set to start in passive mode; otherwise you may need to run
      Xconfig from the Exceed program menu and change the communication mode).  
  </li><li>Run the SSH client and open a shell on the remote machine that you want to
      run X applications from.
  </li><li>Run the application (e.g. "xterm", "xclock", "xeyes", etc.).  If everything
      is configured properly, the application window should appear on your screen.
</li></ol>
<p>
<b>Note</b>: SSH tunnelling may slow down your connection slightly on the local
   network.  However, it can provide a significant <i>increase</i> in speed over
   modem connections if you turn on compression in the SSH client.

<a name="xdmcp"></a>
</p><h3>Using&nbsp;XDMCP&nbsp;to&nbsp;Establish&nbsp;a&nbsp;Session</h3>
<p>This method is less highly recommended, but still better than an unmanaged connection
   (see below).  To start an X session using XDMCP:<br>
</p><ol>
  <li>First, configure Exceed to use XDMCP mode by running Xconfig from the Exceed
      program group and changing the communication mode.  You may choose either
      "query" or "broadcast" mode.  Use "query" mode if you will always connect to
      the same server - you will have to click the "Configure" button and type in
      the hostname or IP address of the server.  Use "broadcast" mode if you need
      to connect to more than one server - unless the server is on the same subnet
      as your PC, you will have to edit the "xdmcp.txt" file in the Exceed user
      directory (click "Configure" and click "Edit" in the "XDMCP Broadcast" section
      and add the name of your server to the list).<br>
      <b>Note</b>: If you plan to use one host primarily, but want to use other
      hosts occasionally, configure Exceed for XDMCP query mode and use the
      "Exceed XDMCP-broadcast" icon in the Exceed program group when you need to
      choose a different host. 
  </li><li>Start the Exceed server (from the "Hummingbird Connectivity Vx" desktop
      folder or program group). 
  </li><li>If you are using broadcast mode, a box will appear with a list of servers you
      can connect to - choose the one you want (if it doesn't appear, see the first
      step) and click "OK".
  </li><li>A login window will appear requesting your username and password.  Type your
      username and press &lt;Enter&gt;, then type your password and press &lt;Enter&gt;
      (do not press &lt;Tab&gt;!).
  </li><li>If this login process succeeds, any programs you have set to run at start-up
      should appear (by default you should get a single Xterm window).
</li></ol>
<p>

<a name="nonxdm"></a>
</p><h3>Using&nbsp;an&nbsp;Unmanaged&nbsp;Connection</h3>
<p>This method is not recommended, but may be necessary or expedient if a host you
need to use do not support SSH or XDM connections.  <b>If you expect to use the this
method regularly, consult your department's server administrator or User Services
staff to determine ways to improve your system security</b>.<br>
</p><ol>
  <li>Run Xconfig and in the "Security" sub-menu set "Host Access Control List" to
      "File".  Click the "Edit" button to the right of the "File:" option and add
      the name of the machine you want to run programs on.  Save the file and exit
      the text editor and click OK in the Xconfig window.
  </li><li>In the Exceed program group (in "Hummingbird Connectivity Vx" on the
      desktop or in the Program menu), run "XStart".  Fill in the information
      pertinent to this session: at the very least, you need to set the "Start
      Method" (the default, "REXEC", should work in most cases) and a command.
      The command must take the form:<br>
      <pre>      setenv DISPLAY @d; <i>command</i>
      </pre>
      The first part up to the semi-colon sets the display variable on the remote
      system to point back to your PC.  Once that is set, a command can be issued
      and the specified program should run and display on your PC.  For instance:<br>
      <pre>      setenv DISPLAY @d; xterm
      </pre>
      will open an X-terminal window.  Click "Login Info" near the bottom, then
      click "Run!" in the meun bar.
  </li><li>A login window will appear requesting a host system, your username and
      password, and an application command.  Fill in any fields that aren't
      already filled in correctly, and click OK.
  </li><li>If the login process succeeds, the program you specified should appear on
      your screen.
  </li><li>You can save the settings entered in the initial window into a .xs file,
      so that they can be recalled for future use.
</li></ol>
<p>
<b>NOTE</b>: If you already have one or more X windows open, attempting to open
open additional windows via the method described above will cause a dialog box to
pop up stating that the server is already running and asking if you'd like to
re-start it. Click <b>No</b>.  Clicking <b>Yes</b> will close all of your currently
open X windows.
</p><p>
<b>ALSO NOTE</b>: you can not mix unmanaged connections in the same session with
   XDMCP-managed connections - attempting to start one while the other type is
   running will require a server reset, which will kill all of your open X windows.

The following items address minor configuration settings which you may want to change
   from the defaults:
</p><p>

<!--
<a name="neighborhood"></a>
<h3>Getting Rid of "Hummingbird Neighborhood"</h3>
The "Hummingbird Neighborhood" icon is part of the Hummingbird HostExplorer suite
of tools, which is installed with Exceed by default unless you choose the "Custom"
installation option and deselect it.  If you want to remove this icon from the
desktop, you must find the program "hntune" on your machine
(under C:\Program&nbsp;Files\Hummingbird\Connectivity\Vx\HostExplorer\FTP),
run it, and set the "Hummingbird Neighborhood should appear in" option to
"My Computer".  You will then be prompted to reboot - if you do not reboot, you
will have to re-run "hntune" again later when you are prepared to reboot in order
to effect the change.
<br>
<b>Note</b>: There is no way to entirely remove this icon, unfortunately, other
   than uninstalling all Hummingbird HostExplorer components which can be done
   from the add/remove programs menu by choosing "Hummingbird Exceed Vx",
   clicking "Add/Remove" (or "Change" in Windows 2000/XP), choosing the "Modify"
   option, and choosing "This component will be unavailable" for the top-level
   HostExplorer checkbox.
<p>
-->

<a name="taskbar"></a>
</p><h3>Toggling Taskbar / System Tray Icon</h3>
You can make the Exceed "X" icon appear in the system tray (bottom left of the
screen, near the clock) rather than in the taskbar when the Exceed server is
running.  To toggle this behavior, right-click on the icon in the tray or taskbar
and select the "Tools" menu and then "Show(Hide) Main Icon".  Exceed (usually)
remembers this setting from one use to the next.
<p>

<a name="toolbar"></a>
</p><h3>Showing / Hiding the Toolbar</h3>
Exceed has a toolbar, which you probably saw pop up the first time you ran
Exceed after installation.  Once you close it, it will not open automatically
on subsequent runs.  To re-activate the toolbar, right-click on the Exceed "X"
icon in the taskbar or system tray and select "Tools", then "Toolbar", then
"Show".  You can also customize this toolbar by choosing "Customize" from this
sub-menu.

<a name="components"></a>
<h3>Adding / Removing Components</h3>
The "typical" option in the Exceed installer leaves out many non-essential
components, and the installation instructions recommend an even further
culled set of features.  If, after installation, you wish to add or remove
components, open the Add/Remove Programs control panel, choose "Hummingbird
Exceed Vx", click "Add/Remove" (or "Change" in Windows 2000/XP), choose
the "Modify" option, and select the items that you want to add or remove.
You will need to re-insert the Exceed CD (or re-extract the installation
files if you bought and downloaded Exceed from the web and deleted the
installation files after running the installer).<br>
<b>Note</b>: After adding or removing any components, you should re-run
Hummingbird Update (<a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#updates">see above</a>) to ensure that all
components are up-to-date.

<a name="tuning"></a>
<h3>Tuning Exceed (XPerf)</h3>
When you install Exceed it gives you the option to run XPerf, which attempts
to tune Exceed for the best performance for your particular graphics hardware.
If you skipped this step, or change hardware, then you may want to run XPerf
again.  To do so, run <b>XConfig</b> (on the Programs menu under "Hummingbird
Connectivity Vx/Exceed"), choose "Other Server Settings" (or "Performance"
if you are viewing configuration options in "classic" mode), and click the
"Tune" button.

<p>
<a name="quitting"></a>
</p><h2>Quitting&nbsp;Exceed&nbsp;and&nbsp;Logging&nbsp;Out</h2>
[<a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#top">top of page</a>]&nbsp;&nbsp;&nbsp;
[<a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#housekeeping">previous&nbsp;section</a>]&nbsp;&nbsp;&nbsp;
[<a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#connecting">next&nbsp;section</a>]<p>
All X windows are terminated whenever you exit or restart the Exceed server,
regardless of which connection method you use.  To exit the Exceed server:<br>
</p><ul>
  <li>If the Exceed "X" icon is in the taskbar, right-click on it and select "Close".
  </li><li>If the icon is the system tray, right-click it, choose "File" and then "Exit".
</li></ul>
To reset the Exceed server (close all X windows and restart the server),
right-click the Exceed icon, choose "Tools", and then "Server Reset".
<p>
If your session is managed by XDMCP (<a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#xdmcp">see above</a>), you can also
shutdown the Exceed server by closing the <b>controlling</b> X window.  The controlling
window is whichever application is listed last in your .xsession file in your composers
account, without a trailing ampersand (&amp;).  (If you have the default .xsession file, the
last and only application that is started is an xterm window).  All other X windows you
have opened will be automatically terminated and you will be logged out.</p><p>
<b>Note</b>: When you are done with your work and ready to quit, make sure that the
Exceed server is completely shutdown (no "X" icon in your taskbar or system tray).
Otherwise you may inadvertantly leave unwanted processes running on the remote system.

<ul>
  <li><b>On the University's central systems (Copland, Strauss, and Mahler) you can use
         the following shortcuts at any shell prompt to open a new program on another of
         the composers:</b><br><br>
         At the shell prompt (%) in an Xterm window, type:
         <dir><dir>
         <b><tt>onstrauss&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
         </tt></b>to connect to Strauss.<br>
         <b><tt>oncopland&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
         </tt></b>to connect to Copland.<br>
         <b><tt>onmahler&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
         </tt></b> to connect to Mahler.<br>
         </dir></dir>
      <p>These commands are especially useful if you log into copland initially (where you
         can't run a lot of software, such as compilers) and then want to run something on
         Strauss/Mahler.  The command "on<i>host</i>" by itself will open an Xterm window.
         Appending a command (e.g. "oncopland&nbsp;netscape") will run that command on the
         specified host.  These commands will work only if you already have completed the
         steps outlined in <a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-UNIX-files.html">
         Customizing Your Composers Account</a>.  You can
         create the aliases manually by editing the <b>.alias</b> file in your directory 
         on the composers and add the following lines:
         </p><dir><dir><b><tt>
         alias onstrauss 'xrsh -auth none strauss'<br>
         alias oncopland 'xrsh -auth none copland'<br>
         alias onmahler 'xrsh -auth none mahler'<br>
         </tt></b></dir></dir>
      <p>After you've made the changes, you must type the UNIX command:
         </p><dir><dir><b><tt>
         source ~/.alias
         </tt></b></dir></dir>
      <p>to make the changes take effect (or log out and log back in again).<br><br>
  </p></li><li><b>Connecting to other hosts:</b><br><br>
      From a shell on any of the composers (or any other system which has xrsh installed),
      you can open an xterm or other X application on another system by typing:<p>
        </p><dir><dir><b><tt>
        xrsh <i>hostname</i> [<i>application</i>]
        </tt></b></dir></dir><br>
      (replacing <i>hostname</i> with the target machine's name, and <i>application</i>
      with an (optional) application to run - if no application is given, an Xterm is
      opened); or
        <b><tt></tt></b><tt></tt><dir><tt><b></b></tt><dir><tt><b>
        xrsh -l <i>username hostname</i> [<i>application</i>]
        </b></tt></dir></dir><br>
      (where <i>hostname</i> and <i>application</i> are the same as above and <i>username</i>
      is replaced with your username <b>on the target machine</b>) - use this form when your
      username on the target system is different than your username on the composers).
      <br><br>
      To use <b>xrsh</b>, you must have a properly configured .rhosts file on the
      system to which you are connecting. If <b>xrsh</b> fails, use the special telnet 
      <b>tnxhost</b> alias:<p>
        </p><dir><dir><b><tt>
        tnxhost <i>hostname</i>
        </tt></b></dir></dir><br>
      (replacing hostname with the machine's name).
      This alias is created on your UNIX account when you get the special UNIX files described
      in the document
      <a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-UNIX-files.html">
      Customizing&nbsp;Your&nbsp;Composers&nbsp;Account</a>.
</li></ul>
<p>
<b>Warning</b>: using xrsh between the composers is relatively secure because the connections
   only traverse dedicated paths between those machines.  Using xrsh/tnxhost between the
   composers and other hosts is <i>not</i> recommended, because these connection methods are
   insecure.  X11 tunnelling via SSH is the recommended connection method for all hosts.
   Using SSH w/tunnelling, you can open multiple secure shell sessions to different hosts
   simultaneously, and run X applications on each of these hosts.

X applications that require you to press the middle mouse-button of a
3-button mouse can still be used with a 2-button mouse. Simultaneously press
both buttons of your 2-button mouse to emulate the 3-button mouse's middle button.
(In order for this third-button emulation to work, it must be turned on in the
Exceed configuration.  For more information see the Mouse section of
<a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-configuring.html">Configuring&nbsp;Exceed</a>.)</p><p>
If you have a wheel mouse, you can press down on the wheel for the third button.

In X applications that run in an Xterm window, you can copy and paste
within the same Xterm window or between Xterm windows by first highlighting
the section to be copied. Paste the highlighted area into an Xterm window by
pressing the middle mouse-button, just as you would on an X-terminal. The
pasting occurs at the point designated by the X cursor. Instructions above
describe how to press the <a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#mousebutton">middle&nbsp;mouse-button</a> when
you're using a 2-button mouse.
</p><p>In Microsoft Windows applications (e.g., Word, Excel) you generally
highlight a section and then press <b>Ctrl-X</b>, <b>Ctrl-C</b>, and <b>Ctrl-V</b>
to cut, copy, and paste within or between Microsoft Windows application windows.
(You may also use the entries on the <b>Edit</b> menu in most applications.)
</p><p>After customizing your central systems account as described in 
<a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-UNIX-files.html">
Customizing&nbsp;Your&nbsp;Composers&nbsp;Account</a> you can
also cut, copy and paste between Microsoft Windows and X windows as follows:
</p><ul>
  <li>To copy (or cut) from a Microsoft Windows window to an Xterm window:
  <ol>
    <li>Highlight the desired section of the Microsoft Windows window
        and press <b>Ctrl-C</b> (<b>Ctrl-X</b> to cut).
    </li><li>Click once in the Xterm window (taking care not to highlight
        anything in the Xterm window) and press <b>Alt-V</b>.  There are
        two <b>Alt</b> keys on most PC keyboards.  You <i>must</i> use the
        one to the right of the spacebar.  Alternately, click the middle
        mouse button (or both buttons if you don't have a middle button
        or scroll wheel - <a href="http://www.udel.edu/topics/connect/sw/exceed/docs/UD-Exceed-how-to-use.html#mousebutton">see above</a>).
  </li></ol>
</li></ul>

<ul>
  <li>To copy (or cut) from a Xterm window to a Microsoft Windows window:
  <ol>
    <li>Highlight the desired section of the Xterm window, and press <b>Alt-C</b>
        (<b>Alt-X</b> to cut).  Make sure you use the right-hand <b>Alt</b> key!
        <b>NOTE</b>: do not move the mouse pointer before you press <b>Alt-C</b>
        (or <b>Alt-X</b>).
    </li><li>Click once in the Microsoft Windows window (or highlight the text to be
        replaced) and press <b>Ctrl-V</b>.
  </li></ol>
</li></ul>

<b>NOTE</b>: When copying from any X application that runs in its own window
      (not an Xterm window) you may need to use that program's own cut/copy/paste
      key combinations. These can be determined from the <b>Edit</b> menu entries
      for the individual X application.
